Center of mass and momentum Questions and Answers

A big ball, mass M=10m, speed v, strikes a small ball, mass m, at rest. Could the following occur: The big ball comes to a complete stop and the small ball takes off with speed 5v? Assuming frictionless surface.
A. Yes, this can occur.
B. No, it cannot occur because it would violate momentum conservation
C. No, it cannot occur because it would violate conservation of energy.
D. can't be determined from the given information.

If the velocity of a pitched ball has a magnitude of 43.0 m/s and the batted ball's velocity is 59.5 m/s in the opposite direction, find the magnitude of the change in momentum of the ball and of the impulse applied to it by the bat.
Express your answer to three significant figures and include the appropriate units.
If the ball remains in contact with the bat for 2.5 ms, find the magnitude of the average force applied by the bat.
Express your answer to two significant figures and include the appropriate units.
